Title: Improvements in or relating to separating particles from cereal grains by an air stream
IPC: B02C11/08
Filed: 1951-08-23
Abstract: 711,291. Treating grain. SAFETY CAR HEATING & LIGHTING CO., Inc. Aug. 23, 1951 [Sept. 9, 1950], No. 19941/51. Class 58. [Also in Group II] An apparatus for separating particles from cereal grains by an air stream comprises an annular air channel formed by two concentric members, means for causing the grains to flow in a thin flat stream across an annular air gap formed between the top and bottom of the channel, an air inlet connected to the bottom of the channel, an exhaust conduit connected to the upper end of the channel at one side thereof, and a baffle element connected to one of the members and wholly disposed in the channel between the inlet aperture and the exhaust conduit, the baffle having a portion that is relatively wider than the remainder of the baffle, the wider portion being disposed in the exhaust conduit side of the channel to reduce the air velocity at those portions of the gap underlying the wider portion of the baffle element. In an apparatus in which the partial-separating apparatus is combined with a milling machine as shown grain is fed through inlets 12, 13 controlled by valves 12a, 13a respectively onto a rotor 14 rotatably mounted in a casing 11 and provided in planes passing through its axis with a plurality of blades 16 to impel the grain outwardly against a detachably mounted liner 17 provided with angularly disposed impact surfaces 18 so that broken grains are directed downwardly into an inwardly tapering frustoconical shell 21 and eventually fall down a cone 22 into an air duct 28 at G up which an air flow is drawn, maintained uniform by a baffle 49a of varying thickness mounted in the duct 28, and of sufficient velocity to remove the lighter impurities which are exhausted through a valve controlled exhaust 29 to which is attached the suct'on fan. The grain falls into the upper end of a discharge passage 53, formed as an outer cylindrical shell within which is a concentric shell 54 forming the air inlet for the apparatus and passes down a helical-shaped strip 57 to any suitable discharge conduit 65, Fig. 4 (not shown) for removal. The shells 53, 54 are so arranged in conjunction with an air distributer 36 fixed under the cone 22 that the material falling from C down the passage 28 passes directly into the discharge passage 53 at a point below the entrance of air into the distributer 36 thus preventing any of the grain from passing through the air distributer into the air inlet 54. Specification 686,124, [Group II], is referred to.

Abstract: 959,226. Semi-conductor devices. SIEMENSSCHUCKERTWERKE A.G. June 8, 1961 [June 9, 1960], No. 20849/61. Heading H1K. In the manufacture of a semi-conductor device a sub-assembly comprising a semiconductor body and an auxiliary member with an electrode between them is soldered to a supporting member by a layer of solder more than 0.1 mm. thick with the auxiliary member nearest the solder layer. In the example, an element 2 consisting of molybdenum plates 3, 4 coated with iron-nickel-cobalt alloy, a highresistivity silicon wafer 2a, a layer 2c of goldantimony alloy, and a layer 2d of aluminium, all bonded together and hard soldered to a copper plate 5, is soldered to a copper-mounting stud 1. A layer of zinc-cadmium solder is then provided on the recessed part of the stud, including the further recess 7 which is at least as deep as the desired final thickness of the solder. The solder is melted before or after placing the element 2 in the recess and during soldering the element is reciprocated to break up any oxide layer on the solder and thus ensure wetting of the surfaces to be joined. As an alternative, the solder prior to final solidification is subjected to ultrasonic vibration. Instead of using a recess 7 the stud may be provided with projections to guarantee a minimum thickness of solder.

Title: Method of and apparatus for providing ringing current in a telecommunications exchange
IPC: H04M19/02
Filed: 1978-05-22
Abstract: In centrally controlled telephone switching systems in which junction circuits (VSI1-VSIx) of the same type are divided into groups (GI) and all the junction circuits are supplied by a ringing current generator (REI), the supply is taken over by a second ringing current generator if a failure occurs. Considerable circuit and wiring cost is required to safeguard the ringing current supply. This is avoided by permanently allocating a single ringing current generator in each case to each group (GI) of junction circuits (VSI1-VSIx), by marking all the junction circuits (VSI1-VSIx) of this group (GI) as defective if a ringing current generator (REI) fails and then by forwarding an incoming request to a free junction circuit of a different group (GII). <IMAGE>

Title: Process for the production of ferromanganese from low-grade manganese-bearing materials
IPC: C21C7/00
Filed: 1956-07-09
Abstract: A ferromanganese product is produced from ore comprising oxides of manganese, iron, calcium and silicon by calcining the ore, charging it into a covered electric furnace on to the surface of a molten slag bath, subjecting the charge to the action of a carbonaceous reducing agent within the furnace at a temperature in the range 1300-1500 DEG C. to reduce to the metallic state iron in excess of that desired in the ferromanganese product and to form a molten slag containing substantially all the manganese of the original ore in the form of manganese silicate and a molten iron product containing impurities from the ore, the slag having a base to acid ratio in the range 0.8-1.5 molecules of base (including manganese oxide as a base) to 1 molecule of silica, passing the slag to a second covered electric furnace for reduction within the same temperature range by means of carbonaceous or non-carbonaceous reducing agent to produce a ferromanganese product, the temperature in both furnaces being controlled by maintaining the arcing tips of the electrodes from 1/2 inch above to 3 inches below the upper surfaces of the molten slag baths therein.  The product of the second furnace operation may be a ferromanganese-silicon containing, e.g. 18-45% of silicon, this product being used in a third furnace operation as reducing agent for manganese silicate from a first furnace operation to produce a low or medium carbon ferromanganese.  In the second furnace operation calcium carbide may wholly or partly replace the carbonaceous reducing agent.  Basic fluxing material in the form of calcium oxide and coke may be added in the second furnace operation to ensure the formation of a small amount of calcium carbide in the residual slag. Specifications 762,469 and 820,241 are referred to.
